MACHINE FOR MAKING WIRE BRACES.

SPECIFICATION forming part of Letters Patent No. 434,311, dated August12, 1890.

Application filed May 20, 1890.

To all whom it may concern:

Be it known that I, LUNA J. ADERHOLD, re-

siding at \Vaco, in the county of I-laralson tion.

I a machine which will quickly and effectually My invention has for itsobject to provide operate to bend up and straighten wire into V-bracessuitable for use as bed and fence braces; and it consists in thepeculiar combination and novel arrangement of parts, all of which willhereinafter be fully described in the annexed specification, andparticularly pointed out in the claims, reference being had to theaccompanying drawings, in which- Figure 1 is a perspective view of myimproved device. Fig. 2 is a top plan view thereof, illustrating indotted lines the several positions of the revolving lever during theoperation of bending the wire; and Fig. 3 is a perspective view of oneof the finished bed-braces.

In the drawings, A indicates a frame or bed-piece, which is suitablyfastened upon a bench,table, or standard,upon the upper face of whichnear one end is mounted to revolve upon a central pivot b a lever B, oneend B of which is adapted to be normally over the front edge of thebed-piece A, said end B carrying the twisting devices, hereinafterreferred to, the opposite end of which is provided with a verticalroller or guide 0, in advance of which is disposed a guide-finger D,which serves to lead the wire to the roller 0, when the lever B isoperated in the manner presently described.

In advance of the twisting devices on the end B and pointing in adirection opposite the finger D is arranged a similar guide-finger E,which serves to guide the free end of,

the wire to the twisting devices, the operation thereof being clearlyunderstood by reference to the dotted lines in Fig. 2 of the drawings.

In operation the wire, which is mounted upon a suitable spool, which, ifdesired, may be secured on the bed-plate A, or it may be held in anyother suitable manner, has its free end passed through a guide-loop Fnear the inner end of thebed A. It is then passed through alaterally-swinging loop or guide G,

and thence to the bent end h of a crank-shaft H, mounted in bearings h hon the end B of the lever, and which forms one of the twisting devices.By looping said free end of the wire over the said end and holding theend by means of pliersor otherwise and turning the crank-shaft H thesaid end will be twisted about the wire and a stout loop portion 10 willbe formed. By turning thelever B in the direction indicated by the arrowits guide-finger D will force the wire downward in engagement with theroller 0, whereby the wire will be bent at this point as the lever B isturned. As the said lever B continues its revolution, its guide E willengage the wire and cause it to be deflected in the path of the upturnedend j of a twisting device J, which consists of a shaft portionjournaled on the upper face of the end B of the lever, its outer endbeing formed of a weighted eranloarm j, which serves to normally holdthe endj vertical. As the lever B contines its revolution, the wire willbe bent about said end j, and to prevent it coming into contact with theend of the opposite twister I provide a guard-piece L, intermediate ofthe twister-shafts, which is slightly higher than the arm h and servesto hold the wire from coming in contact therewith during the revolutionof the lever, a similar guard-rail H being provided to prevent the wireengaging the end of the section B of the lever. Now when the lever' hasbeen turned back to its normal position the operator grips the wire witha pair of pliers or other convenient tool at a point slightly in advanceof its bend about the end j and cuts the wire in advance of thegripping-point. Then by giving the shaft J several turns the endof thewire will be twisted on the parallel portion of the wire, therebyserving not only to form a complete loop, but, owing to the peculiarmannerin which the wire is held, effectually straightening it out.

As the wire during the operation of the lever B is swung laterallybetween said lever and its point of feed, it is necessary that such wirehave free movement and yet be guided at a point near the inner end ofthe lever, and as a fixed guide at this point would cause the wire tobecome bent abruptly Iprovide a guide G, which is formed substantiallyin the the reference to which it will be seen that it con- S1Si'S of along arm g, a horizontally-extending portion 9 having a pivotalconnection in the bed-piece A, and the forward upturned end formed witha loop or guide 9.

Any suitable means may be employed for revolvlng the lever B; but Iprefer for simplicityto employ the means shown in the drawngs, whichconsist in providing-a main shaft Journaled to the projecting end A ofthe bedplece A, formed with a suitable crank-handle and having agroovedpulleyN mounted thereon, about which an endless chain or .belt islooped, the opposite ends of which are passed over guide-rollers O O andarelooped about a pulley P, mounted 011 the pivotal axis of the lever B,as shown.

From the foregoing description the ad vantages of my improvement willreadily appear, and it will be seen that the same may be constructed ata very small cost and can be read- 1ly put up for operation on anyconvenient bench or table.

Having thus described my invention, what I claim is machine for formingwire braces, comprislng a bed or support, wire-holding de vices, and arevolving lever carrying a fixed gulde at one end and twisting devicesat its opposite end, substantially as and for the purpose described.

2. A device for bending wireiuto V-braces for beds and fences,consisting of a base-piece provided with guides for the wire stock and arevolving lever carrying a guide'roller post at one end and the twistingdevices at the 0pposite end, and means for operating the lever,substantially as shown and described.

3. In a machine for bending wire braces for beds and fences, thecombination, with the bed-piece of the machine provided with a guide orguides for the wire, of the revolving lever B, pivoted on the frame A,formed with a vertical guide at one end and the wire twisters andholders at its opposite end, said twisters consisting of shafts havingupturned ends adapted to engage and hold the Wire, said shafts held torotate on the outer end B of the lever, and means for revolving thelever, substantiallyas and for the purpose described.

4. In a machine for bending wire braces for beds and fences, thecombination, with the bed-piece A and guides mounted thereon, of thelever B, held to revolve on said bed-piece A, said lever provided with afixed guide G at one end, a guide or deflector D, arranged to lead thewire thereto, means for securing one end of the wire to the opposite endof the lever, a twisting device consisting of a shaft J, having anupturned end j, adapted to engage the wire, and means for revolving thelever 13, substantially as shown and described.

5. In a machine of the characterdescribed, the combination of base A,the guides F and G, the lever B, held to revolve on the base A, saidlever provided with a fixed guide 0 at one end, twisting devices held onthe opposite end consisting of the shafts having upturned ends h and 7'and crank-handles, the guides I, and M, arranged on the end I3 of thelever B, and means for revolving said lever, substantiallyas and for thepurpose described.
